Here's a way to get music into a vehicle that does not easily accommodate an in-dash receiver. Mount a shaft-style or DIN chassis receiver into this one-size-fits-all kit, and then attach the kit to the underside of your dash.

You can also use this kit to add a DIN-sized equalizer to a vehicle that only has room for the receiver in the dash.

In most cases, using this kit requires modification to your car and/or the kit itself.

Remember, most vehicles will accommodate a receiver in the dash, not beneath it. Not sure about yours? Try our vehicle selector.

Dimensions: 10"W x 3-1/2"H x 9-1/4"D (including flange); 8-9/16"W x 2-9/16"H x 7-9/16"D (undercarriage only). Warranty: 1 year.

Toy Hauler Conversion

Written By sumbuddie, California on Saturday, November 21, 2015

Crutchfield Customer Review (What's this?)

I had a Kenwood with no where to place it. This product offered a box to put it in. While slightly larger to accommodate different sized radio systems the Kenwood had side screw knobs to install the adjust and take up the space in the install situation as you are dealing with some thing more like a custom build. Here is a video of the finished job so you see what it looks like where i used it, all plugged in with the radio and speaker wire welded in.

Pros: Sturdy plastic with properly placed cutouts for the necessary wires.

Crutchfield Customer Review (What's this?)

This underdash mount was very handy when it came to installing a radio in the glovebox of my 1964 Grand Prix. I had to cut a little off the rear of the case to fit inside the dash and clear the blower box, but overall it worked well and looks much better than an exposed radio case.

Pros: Cheap when bought with a radio or other equipment (50% off)

Crutchfield Customer Review (What's this?)

The kit worked out great for my use. I used it in my workshop on the rafters...it"s at a level that is easy to get to, but out of the way of the work area. The kit made it look like a craftsman did it.

Pros: Nice looks and easy to install

Cons: None

Crutchfield Customer Review (What's this?)

Well made with many installation configurations, I couldn't get it to fit under my dash as I had the 4x4 shifter and the c.b. radio in the way. I have a cloth type dash and I velcroed it right on top of the dash! Works great easy access and low enough not to interfere with my vision.

Pros: Many possibilities of installing in different places, also you can trim the back half off for clearance issues.

Cons: No attachment hardware included.

worked well in my boat.

Written By Dave G, Cincinnati on Thursday, August 21, 2014

Crutchfield Customer Review (What's this?)

Encloses the entire in-dash unit and mounts easily under the main console of the boat. It is a no frills product that did exactly what I needed.

Under Dash Box That Did The Trick

Written By Mike S., Fayetteville, NC on Friday, May 23, 2014

Crutchfield Customer Review (What's this?)

The Universal Underdash Kit was included as a no-charge accessory with my purchase, primarily because I asked for it and because no wiring harness adapter is available for my vehicle (1969 Chevrolet Caprice).

Pros: Mounting holes are plentiful. Mounting screws included in kit.

Cons: None, this kit did what I needed it to do, hold my new Head Unit under the dash.

Crutchfield Customer Review (What's this?)

If you require something CLEAN, NEAT and APPEALING to put your new stereo in and the location you are placing it in (Car, Boat or RV etc.) this is what you need. Makes the stereo look like a factory installation.

Pros: Simple, makes it look like a factory install.

Cons: 1 color, Black

Crutchfield Customer Review (What's this?)

I purchased this underdash kit to house a Dual XML8150 in the rear of my 2008 Ford E350 which is converted into a motocross bike race bike hauler. The mount is located directly under a shelf unit on the partition wall. Worked perfect!

Pros: Good fit and finish and looks to be durable.

Cons: None

Tent Trailer

Written By Anonymous, Califorina on Thursday, June 17, 2010

Used this to install a stereo in the tent trailer so we could remove the I pods
from the kids ears and we could enjoy music together. It had enough room behind
the stereo to hide all the wires and made for a nice clean install.

Worked Great

Written By Joe, Wisconsin on Sunday, March 15, 2009

Crutchfield Customer Review (What's this?)

Did just what I needed it to do. Mounted a car stereo under a shelf in the maintenance shop at work. Added a 12 volt 5 amp power supply for portable coolers. Added a pair of home speakers and a car antenna, nice durable NEAT looking shop radio. The kit worked flawlessly, no troubles. In the end it looks and works great. Thanks for another great product, Crutchfield!

Unit worked perfectly...Used it to mount a din radio in a farm tractor that had an old-style shaft radio long since deceased...Shaft style radios are almost impossible to find...Found this unit and decided to give it a try...Unit is sturdy and fit my new radio perfectly...I'm now in the modern world!!!

Marine Installation

Written By Sebastian, San Francisco Bay, CA on Tuesday, September 19, 2006

Crutchfield Customer Review (What's this?)

I just used this under dash kit to install a marine stereo in my sailboat. It fit well, offered a secure, protected mount and everything went as planned. Best of all, it was offered free of charge by Crutchfield, with my stereo and speakers.

Only comment - I wish it had been available in white.

Universal Underdash Kit

Written By Bronco1967, Washington State on Saturday, July 22, 2006

This adapter lets you put the latest tunes in your classic ride. I didn't have to hack my dash to install a DIN mount receiver. I was able to keep the stock radio in its stock location, for maximum classic resale value, not that I would ever part with my Bronco. This kit makes a good, clean, mount. Easy to paint to match your interior too.
